SNOWPLOW.

Application filed February 27, 1928. Serial No. 257,875.

The invention relates to a new and improved form of snow plow tobepreferably drawn by a team, provision being made whereby the plow isheld to its course and cannot slide laterally. v

It is one obj ect of the invention to provide a snow plow ofthe generaltype having a scraping blade and a pair of runners, in which novelprovision is made for permitting the blade to be swung forwardly orrearwardly to vary the width of out, according to the width of the roador. the depth of snow and consequent resistance to pull.

In its preferred form of construction, the plow embodies a relativelylong and. a comparatively short runner between which the scraping bladeextends, and it is a further object to provide unique means for raisingthe front end of the long runner when the plow is to be turned, thusgreatly facilitating lVith the foregoing and minor objects in view, theinvention resides in the novel subject matter hereinafter described Iand claimed, description being accomplished by reference to the;accompanying drawings.-

Fig. 1 is a top planvlew.

Fig. 2 is a side elevation.

Fig. 3 is a fragmentary longitudinal section on line 3-3 of Fig. 1. a i

Figs. 4 and 5 are detail longitudinal sectional views on thecorrespondingly num-- bered lines of Fig. 1. Figs. (Sand 7 are detailvertical transverse sections on lines 6-6 and 7- -7 of Fig. 4. Fig. 8 isa transverse sectional view on line 8-8 of Fig. 1. i

Fig. 9 is a small plan view showing'the machine adjusted for a narrowcut.

The preferred details of construction have beenillustrated and whilethese details will be herein specifically explained, it is to beunderstood thatwithin the scope of the invention as claimed, variationsmay be madel The numeral 10 denotes a relativelylong runner preferablyformed primarily of a length of channel metal, the front end of sa drunner being provided with an appropriate hitchll. Hinged to the frontportion of the runner 10-is a suitably shaped scraping blade 12 having asteel cutting edge 13, said blade projecting laterally and rearwardlywith regard to said runner. Behind the rear end of the blade 12, is acomparatively short'runner 14 preferably formed of channel metal, saidrear end of the blade 12 being hingedly connected with the front end ofsaid 'runner 14. Between the two runners 10-14 is a horizontal plate 15having a plurality of bolt holes 16 at spaced points. Two inwardlyconverging, transverse bars 17-18, are secured at their outer ends tothe runner 14 and at their inner ends to the plate 15. Two similarlyconverging transverse bars 19-20 are secured at their outer ends to therunner 10.

The inner ends of these bars may well overlap each other and lie uponthe plate 15 and a bolt 21 is passed through the innerends of thesebars, said bolt being receivable in any of the openings 16. When thisbolt is removed, the blade 12 may be swung forwardly or rearwardly todispose its outer end at thedesired distance from the runner 10, thusregulating the width of cut. Then, after proper adjustment has beenmade, the parts are again secured by reinsertion of the bolt 21 in theproper opening.

. The hinge axes of the blade 12 are inclined rearwardly and areparallel with each other, and this relation of axes has a tendency'toincline the short runner 14 in one direction or the other, when theblade 12 is swung forwardly or rearwardly. To overcome this tendency,instead of hinging the outer or rear end of the scraper 12 directly tothe runner 14, Ihinge it to a horizontally elongated plate 22 as shownmost clearly in Figs. 1 and 5, the plate being connected with the runnerby bolts 23 passing through vertical slots 24.

When these bolts are loosened, swinging of the blade 12 will incline theplate 22 somewhat, but the runner 14 will remainhorizontal. Then, afterproper setting has been effected, these bolts are again tightened.'Appropriate braces 25 are provided for the blade 12, the rear ends ofthese braces being adjustably secured as'at 26, to permit any necessarymovements of them during setting of the plowvwith the blade 12 at oneangle. or another.

In the present showing, two curved reinforcing bars 2728 are, secured tothe rear side of the blade 12 at its outer and inner ends respectively,and the braces are connected with the upper portions of these bars.Between their ends, the bars 2728 are provided with rearwardlyprojecting lugs 2980 respectively. Lug 29 is received be tween and isspaced from upper and lower forwardly projecting lugs 31-32 on the plate22. Lug is similarly received between vertically spaced lugs 3334 onaplate 35 which is secured to the runner 10. Vertical screws 36-37 areswiveled in the lugs 3132 and 33-34 respectively, and are threadedthrough the lugs 29-30, said screws having hand wheels or the like 38,By rotat-ing these hand wheels, the entire blade 12 is raised or loweredas required.

Front andrear plates 39-40 contact with the outer side ofthe runner 1O'and project downwardly below the same to bite into the snow and holdsaid runner against lateral slippage, said plates being preferablysecured to the runner by appropriato'bolt and slot connections 41. Asimilarplate 42 is disposed at the inner side of the channel metalrunner 14 and is secured by a bolt and slot connection 43, to thevertical flange 44 of an angle metal bar which extends longitudinally ofsaid runner 14, in opposed relation with the vertical webofthe latter.The base 45 of this angle metal bar is secured by rivets or the like 46upon the base flange 47 of the runner 14.

Near itsfront end, the lower 'edgeot the runner 10 is formed with alongitudinally extending notch 48. WVithin this notch, is

a turning shoe 49 which is swiveled on the lower end ofa vertical screw50 carried by the runner 10. Normally," shoe 49 is confined totallywithin the notch'48. When the entire plow is to "be turned around orotherwise turned however, the screw 50 is operated to tion of thevertical web of the channel metal bar, of which the runnerlO is formed,and

p I cut awaya length of the base flange 51 of this bar, of less lengthhowever than the notch, leaving a portion 52 of said base flangeprojecting beyond the-rear edge of said notch. This base flange portionis curved upwardly as shown at 52 and is riveted or otherwise secured tothe rear end of a horizontal plate 53. Between the front portion of thisplate and the top flange 54 of the runner 10, is a vertical sleeve 55'which ispreferably flanged a single met-al'bar.

" be made, as above "stated;

at its ends at '56 and riveted or otherwise secured to said flange 54and plate 53. This flange and plate are formed with openings alined withthe sleeve, and the screw 50 passes through said openings and sleeve,being threaded into the latter. As above described, the shoe 49 isswivelled upon the lower end of this screw and when the shoe is idle, itmay well contact tightly with the lower side of. the plate j I prefer toform the shoe'49prihcipally of This bar'is bent between its ends toprovide upper and lower horizontal portions 57-58, integrally "connectedat their rear ends by 'asp'acingportion 59 The tront'end 60 of theportion 58is curved u pwardly and the front end ofthe portion 57 isbentdo'wnwa'rdly at 61 and secured to said end 60,"being then extendedrearwardly as at 62 and securedto a verse-alarm lilwhich is maybepreventedbya cotter pin- 01 the like 64 passed through said screw,-torinstancqunw der-the bar portion62.

Preferably, the runner 10 'is provided with an'appropriate seat 65torthe driver, as his weight assistsmaterially m' holdmg the plow on itscourse. 7
